FAQ

What is a good reaction time?

Average human reaction to a visual cue is about 200–250 ms. Under 200 ms is fast; top gamers and athletes can reach 150 ms or below.

Why did it say too early?

You clicked while the pad was still red, before the green signal. Wait for green — the delay is randomized so you can't predict it.

Does display lag affect the result?

Slightly. Monitor and input latency add a few milliseconds, so results are best compared on the same setup.
